Arbitrary file deletion via CSRF-triggered injection
Published May 28, 2026 · Updated May 28, 2026
Cross-site request forgery in WP Contact Form 7 DB Handler 3.0 and earlier allows attackers to delete arbitrary server files. process_bulk_action validates a nonce only when its POST field exists, interpolates an untrusted ID into SQL, unserializes post_content, and passes unchecked paths to wp_delete_file. Exploitation requires a logged-in administrator to visit an attacker-controlled page; the demonstrated consequence is file deletion rather than code execution.
